Description
Drucksensoren werden in vielen Kontexten verwendet, beispielsweise bei Automobilen, in der Industrie, Medizin, Luftfahrt und in der Unterhaltungselektronik. Beispielsweise werden Drucksensoren im Zusammenhang mit Automobilen dazu verwendet, Luftdruck und Vakuum von Ansaugkrümmern zu messen, und sie können auch beim Einsatz von Airbags und anderen Anwendungen verwendet werden.Pressure sensors are used in many contexts, such as automobiles, industry, medicine, aerospace, and consumer electronics. For example, automobile-based pressure sensors have been used to measure manifold air pressure and vacuum, and may also be used in the deployment of airbags and other applications.
Herkömmliche Drucksensoren werden in Integrierte-Schaltung-Gehäuse (IC-Gehäuse, IC = integrated circuit) eingehäust. Jedoch setzen manche herkömmliche IC-Gehäuse ihre Drucksensoren ungeniert der umliegenden Umgebung aus (z. B. der Luft), sodass der Sensor den Umgebungsdruck messen kann. Ungünstigerweise kann es jedoch zu Problemen kommen, wenn der Drucksensor ungeniert der umliegenden Umgebung ausgesetzt wird. Beispielsweise können Streudrähte oder Schmutz von der umliegenden Umgebung in einen physischen Kontakt mit dem freiliegenden Drucksensor kommen und dadurch ungenaue Druckmessungen oder sogar eine Beschädigung des Drucksensors selbst bewirken. Auch wenn herkömmliche Drucksensoren und ihre dazugehörigen Integrierte-Schaltung-Gehäuse in mancherlei Hinsicht ausreichend sind, haben die Erfinder deshalb verbesserte Drucksensoren und zugehörige Gehäuse, wie sie hierin dargelegt sind, ersonnen.Conventional pressure sensors are housed in integrated circuit (IC) packages. However, some traditional IC packages unabashedly expose their pressure sensors to the surrounding environment (eg, the air) so that the sensor can measure ambient pressure. Unfortunately, however, problems may arise if the pressure sensor is exposed to the surrounding environment unabashedly. For example, stray wires or debris from the surrounding environment may come in physical contact with the exposed pressure sensor and thereby cause inaccurate pressure measurements or even damage to the pressure sensor itself. Although conventional pressure sensors and their associated integrated circuit packages are in some respects sufficient, the inventors have therefore devised improved pressure sensors and associated housings as set forth herein.
Die Aufgabe der vorliegenden Erfindung besteht darin, Vorrichtungen und ein Verfahren mit verbesserten Charakteristika zu liefern.The object of the present invention is to provide devices and a method with improved characteristics.
Die Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Weiterbildungen finden sich in den abhängigen Ansprüchen.The object is solved by the features of the independent claims. Further developments can be found in the dependent claims.
Bevorzugte Ausführungsbeispiele der vorliegenden Erfindung werden nachfolgend bezugnehmend auf die beiliegenden Zeichnungen näher erläutert. Es zeigen:Preferred embodiments of the present invention will be explained below with reference to the accompanying drawings. Show it:
Der beanspruchte Gegenstand wird nun unter Bezugnahme auf die Zeichnungen beschrieben, wobei durchgehend gleiche Bezugszeichen verwendet werden, um auf gleiche Elemente Bezug zu nehmen. In der folgenden Beschreibung sind der Erläuterung halber zahlreiche spezifische Einzelheiten dargelegt, um ein gründliches Verständnis des beanspruchten Gegenstandes zu vermitteln. Es mag jedoch offensichtlich sein, dass der beanspruchte Gegenstand auch ohne diese spezifischen Einzelheiten praktiziert werden kann.The claimed subject matter will now be described with reference to the drawings, wherein like reference numerals will be used throughout to refer to like elements. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be obvious, however, that the claimed subject matter may be practiced without these specific details.
Manche Ausführungsbeispiele der vorliegenden Offenbarung beziehen sich auf verbesserte Gehäuseanordnungen für Druckerfassungselemente. Statt ein Druckerfassungselement ungeniert auf eine Weise, die es für eine Beschädigung aufgrund von Streudrähten, Schmutz und dergleichen anfällig macht, der umliegenden Umgebung auszusetzen, umfassen die hierin offenbarten verbesserten Gehäuseanordnungen eine Abdeckung, die dazu beiträgt, eine Umhüllung um das Druckerfassungselement zu bilden. Die Abdeckung umfasst einen Fluidflusskanal, in dem ein Blockierbauglied angeordnet ist. Der Fluidflusskanal versetzt das Druckerfassungselement in eine Fluidkommunikation mit der äußeren Umgebung, sodass Druckmessungen vorgenommen werden können, während das Blockierbauglied dazu beiträgt, das Druckerfassungselement vor der äußeren Umgebung (z. B. Streudrähten und in gewissem Umfang Schmutz) zu schützen. Auf diese Weise tragen die hierin offenbarten Gehäuseanordnungen dazu bei, genauere und zuverlässigere Druckmessungen zu fördern als bisherige Implementierungen.Some embodiments of the present disclosure relate to improved housing arrangements for pressure sensing elements. Rather than unduly exposing a pressure sensing element to the surrounding environment in a manner that makes it susceptible to damage due to stray wires, dirt, and the like, the improved enclosure arrangements disclosed herein include a cover that helps to form a sheath around the pressure sensing element. The cover includes a fluid flow channel in which a blocking member is disposed. The fluid flow channel places the pressure sensing element in fluid communication with the outside environment so that pressure measurements can be made while the blocking member helps to protect the pressure sensing element from the outside environment (eg, spreader wires and some dirt). In this way, the housing arrangements disclosed herein help promote more accurate and reliable pressure measurements than previous implementations.
Es wird einleuchten, dass sich der Begriff „Fluid”, wie er hierin verwendet wird, auf jegliche Substanz bezieht, die keine feststehende Gestalt aufweist und die einem Außendruck ohne weiteres nachgibt. Beispielsweise kann ein typisches Fluid ein Gas (z. B. Luft) und/oder eine Flüssigkeit (z. B. Wasser) umfassen. Folglich ist ein Fluidflusskanal, wie er hierin offenbart wird, lediglich dahin gehend strukturiert, zu ermöglichen, dass ein Fluid (z. B. Luft und/oder Wasser) durch denselben hindurchwandert, jedoch nicht unbedingt in beiden Richtungen.It will be understood that the term "fluid" as used herein refers to any substance that does not have a fixed shape and that readily yields to an external pressure. For example, a typical fluid may include a gas (eg, air) and / or a liquid (eg, water). Thus, as disclosed herein, a fluid flow channel is merely structured to allow a fluid (eg, air and / or water) to travel therethrough, but not necessarily in both directions.
Ein Ausführungsbeispiel einer Vorrichtung
Das Gehäusesubstrat
Das Druckerfassungselement
Zumindest ein elektrischer Kontakt ist auf einer Außenoberfläche der Gehäuseumhüllung zugänglich und ist dazu konfiguriert, eine elektrische Kommunikation zwischen dem Druckerfassungselement
Die Abdeckung
Der Fluidflusskanal
Um zusätzlichen Schutz vor der umliegenden Umgebung zu bieten, kann über dem Druckerfassungselement
Bei vielen Ausführungsbeispielen weist der Fluidflusskanal eine ausreichende Größe auf, um zu ermöglichen, dass Luft durch denselben fließt, sodass ein Umgebungsdruck gemessen werden kann. Außerdem weist ein Fluidflusskanal oft eine ausreichende Größe auf, um zu ermöglichen, dass Wasser durch denselben fließt (z. B. um ein Abfließen von einer Gehäuseanordnung zu ermöglichen), wodurch eine Wasseransammlung in Gehäusen begrenzt wird. Aufgrund von H2-Bonding und Wasseradhäsionskräften können Aperturen, die einen Fluidflusskanal definieren, einen Durchmesser von zumindest ungefähr 2,5 mm aufweisen, jedoch können Mindestdurchmesser für derartige Löcher je nach dem Material der Abdeckung, der Dicke der Abdeckung, dem abzulassenden Fluid und anderen Faktoren stark variieren.In many embodiments, the fluid flow channel is of sufficient size to allow air to flow therethrough so that ambient pressure can be measured. In addition, a fluid flow channel is often of sufficient size to allow water to flow through it (eg, to allow drainage from a housing assembly), thereby limiting water buildup in housings. Due to H 2 bonding and water adhesion forces, apertures defining a fluid flow channel may have a diameter of at least about 2.5 mm, however, minimum diameters for such holes may vary depending on the material of the cover, the thickness of the cover, the fluid to be vented, and others Factors vary greatly.
Die Abdeckungs- und Gehäuseanordnung kann auch in kompliziertere Geometrien geformt werden, um mit den Außenabmessungen vorhandener Dichtungen, die seitens Kunden bei deren Anwendungen verwendet werden, zusammenzupassen. Bei manchen Ausführungsbeispielen kann das geformte Gehäuse ein weiteres Blockierbauglied oder einen sich windenden Pfad umfassen. Da die Abdeckungs- und Gehäuseanordnung jedoch ihren eigenen Fluidkanal umfasst, kann die Gehäuseanordnung den Raum, der für zukünftige Generationen des geformten Gehäuses für die Anwendung des Kunden (z. B. einen Seitentür-Airbag) benötigt wird, verringern. Somit kann die erfindungsgemäße Abdeckungs- und Gehäuseanordnung das Erfordernis, dass der Fluidkanal in der geformten Gehäuseanordnung den Raum für andere Komponenten freimacht, eliminieren oder verringern. Gleichzeitig kann die Abdeckungs- und Gehäuseanordnung aufgrund ihrer geringen Größe dennoch ein direkter Ersatz für geformte Vorläufer-Seitentür-Airbag-Gehäuse sein.The cover and housing assembly can also be formed into more complicated geometries to match the outer dimensions of existing seals used by customers in their applications. In some embodiments, the molded housing may include another blocking member or a winding path. However, since the cover and housing assembly includes its own fluid channel, the housing assembly can reduce the space needed for future generations of the molded housing for the customer's application (eg, a side door airbag). Thus, the cover and housing assembly of the invention can eliminate or reduce the need for the fluid channel in the molded housing assembly to clear the space for other components. At the same time, due to its small size, the cover and housing assembly may still be a direct replacement for molded forerunner side door airbag enclosures.
